The answer is 9
If the number is considered as 'ABC', the equation is
A+(B-C). So,
231 = 2+(3-1) = 4 and so on.
742 = 7 + (4-2) 9

I've come up with another solution...
here it is
231=4(13+2=15)(5-1=4)
342=5(24+3=27)(7-2=5)
543=6(34+5=39)(9-3=6)
451=8(15+4=19)(9-1=8)
so
742=2(24+7=31)(3-1=2)

I really feel nervous that i didn't spot the obvious solution from the beginning

This is because of the Genius word added to the post title. If the title would have been the "Simple Cracking Code Puzzle", then our mind will try to find the simple solution. However because the title contains the word "Genius", our mind will try to find a complex solution.

In my opinion,the simplier you think,the smarter you are.Thanks for your comments though.

The answer could also be (-2).If you look at the way I substracted the numbers,you will see that in the last one I did it in reverse order.

Yes, you are right. One can take the absolute value or else the answer could be -2.
